STEEL SASH 2 Sheets-Sheet 2 Filed Sept. 5, 1930 Patented May 16, 1933 f*UNITED STATES lmxlfaN'r OFFICE CLARENCE F. KUNNY,y or IBROOKFIELD,WISCONSIN, ASSIGNOB ro lFEDERAL STEEL y SASII COMPANY, OEWAUKESHA,WISCONSIN, A CORPORATION or WISCONSIN STEEL SASH Application filedSeptember .10 provide a steel sash construction which has beenespecially devised for use in sanitary dairy barns andother farmbuildings and which has been found `to satisfactorily meet yserv-icerequirements whereL the usual socalled industrial steel sash has not.1

More particularly the present invention provides a steel sash withoutside glazing so that the inner face of the sash may be readily keptin a sanitary condition and be free as far as possibley fromprojectionsand dust catching and holding surfaces. Furthermore the presentconstruction provides a steel sash with a ventilator section whichswings inwardly and may be held in partiall *2 5 ly open position or beswung to completely open position adjacent the fixed Sash or the wall ofthe building. Also the steel sash as hereinafter described is soconstructed. and arranged as to attain the above described objects in asimple and efficient manner.

The invention further consists in theseveralA features hereinafter setforth and more particularliy defined by claims at the conclusion hereoIn the drawings, Fig. 1 is an elevation view of steel sash embodying theinvention, `as viewed from the interior side thereof,

Fig. 3 is a detail enlarged vertical sectional view taken on the line3-3 of Fig. 1, parts being broken away;

f15 Fig. 4 is a detail, vertical sectional. View taken on the line 4 4of Fig. 1.

Referring to the drawings,-the numeral 5 designates the relatively fixedsash frame which is formed of side and `end T-bars l U which may bewelded or otherwise suitably presentfiat lsurfaces to the interior ofthe 5, 1930. Serial No. 479,897.

securedtogether at the corners so as to form a frame and whichmay haveone or more muntin bars 6 of T `section welded thereto to provide thewindow openings 7 and. which also includes a transverse T-bar 8.

The ventilator section j `9 is formed by T-bars l() joined, as bywelding, at the corners and to a muntin bar 11 of similar section; saidsection being hingedly connected to the bar 8 ofthe main frame by spacedhinges 12 and secured in closed position .by a suitable latch 13cooperating with a keeper 14 on the rmain frame.

For securing a weathering Contact between the fixed sash frame and theventilator `section, the inner sides of the upper opening in the fixedframe that receives the ventilator section have ychannel bars 15 securedthereto as by welding so that the inner sides 16 of said bars form aninner weatherin surfacevagainst which the outer flanges 1 of theventilator section abut and the outer flanges 18 forni a weathering sealywith the ends of the legs 19 of the T-bars 10 ofthe ventilator section.

It will be noted v from Figs". 2 and 3 that when the ventilator isclosed that the construction is such that bars forming the fixed frameand ventilator section are aligned and B0 building and that the windowsl20 for Kthese V' sections are secured in their respective frame byoutside glazing 21 so that substantially the entire interior surface ofthe complete sash is formed of plane flat surfaces and freer vfromcrevices where dirt and dust can collect and 4may be readily andefficiently cleaned by the use of a water hose.

A To providea `water shed at the lower joint of the ventilatorlsectioynI may secure a longitudinally extendingfplate22 to its lower fra-Inemember to projecty over the ljoint asshown in Fig..3. n With thisconstruction also it will be noted thatthe ventilator swings inwardlyand in"5 Fig. 4 I show .the ventilator in closed position infulllinesand the partially .open and fullopenpositions in dotted lines, it beingnoted that for the. partially open position I have provideda latchplatey23 at one Side of 1,00

the ventilator section that cooperates with a notched bar 24 pivotallymounted at 25 on a bracket 26 secured to the lixed frame and adapted tohave any one of its notches en gage the plate 23 to hold the ventilatorin different partially open positions.

It will be noted that the notch in the plate 23 in which the bar 24works permits said bar to be disengaged therefrom so that the ventilatormay be swung to a position substantially parallel to the plane of theixed sash frame.

With the above construction it is a simple matter to keep the innersurfaces of the sash that form a part oi the wall of a dairy barn orother farm building in a sanitary condition, and the full capacity ofthe ventilator is realized when the same is swung down through an angleof substantially one hundred and eighty degrees.

I desire it to be understood that this invention is not to be limited toany particular form or arrangement of parts except in so far as suchlimitations are included in the claims.

What I claim as my invention is:

l. A window comprising an opening in a wall, a frame lining the edges ofsaid` opening and extending around sidewardly to cover interior portionsof said wall adjacent to said opening, said frame having an inwardlyextending yflange in the plane of said wall covering portions, muntinscomposed of dividing webs backed by interior flanges, the latter beingin a plane with said frame iange and joining therewith providing flatinterior frame portions flush with said frame flanges when closed, saidventilator being hingedly mounted in said ventilator opening andarranged to swing inwardly.

3. A window comprising an opening in a wall, a frame lining the edges ofsaid opening and extending around sidewardly to cover interior portionsof said wall adjacent to said opening, said frame having an inwardlyextending flange in the plane of said Wall covering portions, muntinscomposed of dividing webs backed by interior flanges, the latter beingin a plane with said frame flange and joining therewith said muntinsbeing secured to the frame dividing the same into a ventilator openingand Vsmaller sights, panes within said sights seated against theinterior of said frame flanges and said web flanges and embraced by thelining portions of said frame and said webs, exterior glazing forsecuring said panes in said sights, and a ventilator including panesproviding flat interior frame portions flush with said frame flangeswhen closed, said ventilator being hingedly mounted in said ventilatoropening and arranged to swing inwardly, and means for holding theventilator in various partially opened positions and for permitting saidventilator to swing inwardly to a position substantially parallel withthe plane of said Window.

In testimony whereof, I aiiix my signaf ture.
